To Find Experts In Sandblasting Los Angeles Must Be The Place To Visit

By Shawn Hunter


Blasting is an umbrella term referring to processes that involve propelling abrasives against surfaces to clean or shape them. The degree of results is dependent on the force of propulsion. The machine used is called a sandblasting device. When in need for service providers of services of sandblasting Los Angeles should be prioritized.

The first patent for the process was made in 1870, but then the process became widely used making it public knowledge. In fact people have developed different variants for different applications. Sodablasting, wet, bead, dry ice, shot, hydro, wheel, and automated blasting are among the variants. The focus of this article is on the main variants that are in common use today.

Wet blasting was pioneered by someone called Norman Ashworth because of the advantages it offered over its sand counterpart. Sand blasting had been banned by many countries at that time because of the health issues associated with it. Wet blasting allows the use of media of a wide range of densities including plastic and steel. It also removes grease while blasting at the same time. Water helps to wet silicacious materials making their use safe.

Another advantage of wet blasting is the ability to remove dangerous materials like asbestos and radioactive elements without causing harm to the operator of the machine. It is also available in major formats like walk-in booths, total loss portable blasting units, hand cabinets, and automated production machinery. The process can also be done at high speeds comparable to those of its dry counterpart.

Another variant is the wheel blasting. In this variant, the abrasive is propelled against a surface by centrifugal force generated by a wheel. The absence of air or liquid has made this process to be categorized as airless blasting operation. The machine used for this process is called a wheel machine and some of the abrasives that can be used include cut-wire, steel shot, and grit. Different machines have different number of wheels which can be set to different levels of power. Efficiency and speed at which work needs to be done can be set on the machine.

Micro-abrasive blasting is sometimes referred to using the name pencil blasting. This variant makes use of tiny particles. Typical particles have a diameter of between 10 and 150 micrometers. The surface being blasted also has very small diameters, normally a few centimeters in diameter. The abrasive is delivered accurately to the surface in form of a stream. This process has to be done delicately because of its nature.

In dry ice blasting as suggested by the name, frozen carbon dioxide and air are used in the process. Dry ice dislodges surface contaminants by being propelled at very high speeds on surfaces. The freezing effect of dry ice helps to dislodge and break bonds between surfaces and dirt. Sublimation ensures that no surface residue forms afterward.

Generally, this process can be achieved by many machines. The machines vary in various aspects such as efficiency, cost, complexity, and size. There are large machine for use in commercial processes and small ones for private use at home.
